Breed weight ranges are a reference, not a diagnosis. Ask a vet before you treat a number as a problem.

Food
Standard adult cat food with portion control. Mixed cats get fat on free-fed kibble.
Home
Indoor is safer. Scratching posts and a window beat outdoor roaming.
Company
Varies. Many like family; some want one person. Let the cat set the pace.
Coat
Weekly brush. More in spring.
What tends to stress them
- Dirty litter
- Sudden diet changes
- No vertical space
Breed risks to mention to a vet
